OEM Industries AD0424HB-C56 40mm Fan

The OEM Industries AD0424HB-C56 is a 40mm cooling fan designed for compact CPU air cooler installations. It operates on a 24V supply and draws .09A through a 3 pin power connector. The unit uses a ball bearing for rotation and has no LED lighting.

Suited for 24V 3 pin headers only

This fan fits builds that can provide a 24V 3 pin header and have space for a 40mm frame. It is not for systems that lack a 24V fan header or require a 4 pin PWM connector for speed control. Buyers needing a larger frame or a different voltage should look at other models.

24V .09A 3 pin electrical spec

The defining specification is the 24V .09A rating combined with a 3 pin connector. Match this exactly to the header on your board or controller; a mismatch in voltage or pin count will prevent correct operation.

Questions about this item

What 24 V power header do I need on my board or controller for the AD0424HB-C56 to run?

The fan draws 0.09 A from a 24 V source through its three-pin connector, so the header must supply 24 V and at least that current.

Will the three-pin plug on this 40 mm ball-bearing fan fit the older four-pin headers I still use?

Yes, the three-pin connector seats in a standard four-pin header; the fourth pin simply remains unused while power and tachometer signals pass through.

How can I confirm the AD0424HB-C56 is spinning correctly after installation?

Check the motherboard or fan-controller RPM readout — a steady value matching the fan’s normal speed range shows the tachometer wire is reporting rotation.
